The generic evo-one guide has info on all the generic wiring. https://cdn02.fortin.ca/download/68451/rm441-install-guide-68451.pdf
Clutch is a (-)trigger, Blue/orange wire at clutch switch.
Could use dark blue A8 - GWR, green A4 (-)ignition, or white A5 (-)start
Ive considered running a relay off the starter (+) to power the relay which would be triggered by the ebrake signal and that relay would then bypass the clutch switch. The only issue I have with that is if the ebrake is up and car is in gear and someone else gets in my car it will start without the clutch.
dont do this, can be a hazard one day as you said.
